The concept for the FRENZEL JF-5E1 "Champ Pro"  was a plug & play, no-frills, low priced, high quality low power practice amp.  There are no tone stack adjustments.....just a Gain control. You can use your guitar volume and tone controls to get your unique clean and overdrive levels and then set the amp Gain  control for the desired playing level. It can be even be used for small venues or miked through the PA for larger venues by using the post-output transformer Line Out jack. There is an internal load to protect the amp when no speaker is plugged in and to give you speaker simulated tones.  You can also us the Line Out  to drive a solid-state ampp to give you great vintage tube tones. is perfect for those late-late night practice sessions where you don't want to wake the neighbors. You can  unplug the speaker and use headphones. The "Champ Pro" comes with our multi-valve output tube circuit that allows you to use a wide variety of output tubes. It will amaze you with its warm vintage 60's Fender Champ blues tones ....and of course, it is loaded with all the features that the Frenzel amps are famous for.
